About the Glasstron
Display unit
The display unit is equipped with two
small (left and right) LCDs.
Power supply box
You can use Sony’s recommended
optional attery pack. You can also use
the house current. To use the Glasstron,
connect your video equipment to A/V
IN on the power supply ox.
Features
• A powerful, ig screen experience
compara le to watching a 52-inch screen
from approximately 2 m (6.6 feet) away.
• Handy porta le folding display.
• The display unit weighs only 100 g (4 oz).
• Approximate continuous use for up to
seven hours with Sony’s recommended
attery pack, NP-F550.
Caution: The screen is always right in front of you.
The Glasstron is a face-mounted display. With this type of display, the screen is always in front
of you, even if you move your head. Because of this feature, you can concentrate on the screen
more easily compared with ordinary TVs, and you have a sense of eing in the action.
• It is easy to adjust the Glasstron to your eyes. You can use the display unit even while wearing
glasses.
• Every time you use the Glasstron, the adjustment screen appears to help you adjust the
display unit properly. You can also check whether the left and right screen positions are
properly aligned or not.
• If you keep using the Glasstron continuously for three hours, a warning appears on the screen
and the power will turn off automatically.
The Glasstron consists of the following items:

SECTION 3
ELECTRICAL ADJUSTMENTS
Precautions on adjustment:
1. Perform the adjustment in the given order.
2. Power supply voltage: DC 9 V
3. Equipment required
Electrical adjustment requires the following measuring equip-
ment.
(1) Oscilloscope: 2 phenomena, band 30 MHz or more, with de-
lay mode (use 10 : 1 probe unless otherwise specified)
(2) Pattern generator
(3) Regulated power supply
(4) Digital voltmeter
(5) Frequency counter
(6) Connector for adjustment
4. Measurement points for adjustment are located at CN803 on
the RG-A01 board. The pin No. and signal name of CN803 is
listed below.

Note: In the adjustment where the S VIDEO input is designated, if ad-
justment was made with the VIDEO input. The specification of
this set will not be satisfied.Always follow the designation.
If adjustment was made using theVTR with S VIDEO OUT termi-
nal as a signal source, the performance of this set depends on that
VTR. Therefore, use the pattern generator with the Y/C separate
output terminals, if possible.
5. Setting up Input Signals
(1) S VIDEO Signal
Connect an oscilloscope to theY signal pin of the S VIDEO
IN connector, and check that the sync signal of Y signal is
approximately 0.3 V, video amplitude is approximately 0.7
V, and the setup level is 0 V. (If using theVTR with SVIDEO
OUT terminal, check further that the chroma signal and burst
signal do not remain.)
Also, connect an oscilloscope to the chroma signal pin of the
S VIDEO IN connector, and check that the burst signal am-
plitude of chroma signal is approximately 0.3V and it is flat,
and moreover, the amplitude ratio of burst signal to “red”
signal is 0.30 : 0.66.
Setup level: Potential difference between black and pedestal

(2) VIDEO Signal
In adjusting this set, video signals obtained from the pattern
generator are used, and therefore these video output signals
must satisfy the specification. Connect the oscilloscope to
the VIDEO IN terminal, and confirm that the sync signal
amplitude of video signals is approximately 0.3 V, the am-
plitude of video part is approximately 0.7V, burst signal am-
plitude is approximately 0.3V and flat, and the level ratio of
burst signal to “red” signal is 0.30 : 0.66.

[Preparation for Adjustment]
1. Service Jigs
(1) Adjusting remote commander (RM-95-modified)
Note: J-6082-053-B
(2) Extension cable (for remote commander plug converter)
J-6082-291-A
Note: The page will not be changed over, unless the microprocessor in
the adjusting remote commander is a new one (uPD7503-G-C56-
12). In such a case, replace with new microprocessor (8-759-148-
35).
2. Adjusting Remote Commander
For the adjustment, the adjustment data saved in the nonvola-
tile memory (EEPROM) must be rewritten, and for this pur-
pose the adjusting remote commander is used.
The adjusting remote commander makes two-way communi-
cation with the set using a remote control signal line (LANC).
The adjusting remote commander transmits pages, addresses,
and data up/down commands to the set.The set transmits pages,
addresses, and data to the adjusting remote commander.
3. How to Use The Adjusting Remote Commander
(1) Connect the adjusting remote commander to the CN305 on
YM-A01 board via extension cable (J-6082-291-A).
At this time, set the switch of extension cable to OFF
(OPEN) position
Turn ON the power on the set.
(2) Set the HOLD switch on the adjusting remote commander to
the HOLD (SERVICE) position.
If connection is normal, the LCD display on the adjusting
remote commander will be as shown in Fig.3-3.

Press the FF (M) button to increase the address.
Press the REW (m) button to decrease the address.
There are 256 addresses from 00 to FF.
•Data change (data setting)
Press the PLAY (N) button to increase the data.
Press the STOP (x) button to decrease the data.
There are 256 data from 00 to FF.
•Adjustment data writing
The PAUSE button must be pressed to write adjustment
data (D page) to the nonvolatile memory (EEPROM). (Un-
less the PAUSE is pressed, new data are not saved in the
nonvolatile memory.)
(4) Select page: 1, address: 00, and set 01 data. Thus, the data
input to page: D is enabled.
(5) After the adjustment finished, select page: 1, address: 00,
and set 00 data. Thus, the data change on page: D is dis-
abled.
(6) After all adjustments finished, turn OFF the main power sup-
ply (9 V) once.
4. Precaution on Use of TheAdjusting Remote Commander
Misoperation of the adjusting remote commander could erase
correct data. To prevent this, it is recommended to make a note
of data from page: D before adjustment, and also to make a
note of new adjustment data each time the adjustment of one
item is finished.

5. Data Processing
Certain adjustment items require the microprocessor data to be read out or the displayed data (hexadecimal numbers) on jigs or
adjusting remote commander to be calculated to get adjustment data. In such a case, convert hexadecimal numbers into decimal
numbers once, then make calculation, and convert its result into hexadecimal number as adjustment data. Table 3-1 shows hexadeci-
mal –decimal number conversion.

Connection:
Adjustment Procedure:
(1) Connect an oscilloscope to the CN803 pin 3(B OUT) and
pin 1(GND) on the RG-A01 board.
(2) Adjust RV911 (DL-A01 board) so that the Ilevel (B-Y,-
(B-Y) part) of waveform on the oscilloscope becomes the
minimum and also satisfies the specified value.
